Phthalocyanine derivatives specifically designed for fabrication of organic semiconductor gas sensors

This paper describes studies in which metal-free and metal substituted phthalocyanine films were sublimed onto the surfaces of interdigital electrodes in order to measure the change in the conductivity when the coated electrodes were exposed to a series of test gases. Also reported are data on tetracumylphenoxy and tetraoctadecyl ether derivatives of the metal-free and metal substituted phthalocyanines which were synthesized specifically for use as coating materials to be applied one monolayer at a time by the Langmuir-Blodgett (LB) method.
